I'm facing the same issue. Is there any update?

Convert the 8bit encoded mail to quoted-printable before signing It will solve the issue you are facing. Refer this url https://tools.ietf.org/html/rfc4871#section-5.3

Thanks, mine issue was that for some reason "mail.smtp.allow8bitmime" was set to true causing JavaMail to automatically convert messages back to 8bit
